[0002] A drone is an unmanned aerial vehicle controlled by a radio remote control device and a self-contained program control device. Compared with manned aircraft, it has the characteristics of small size, low cost, and easy use. It is widely used in aerial photography, agriculture, plant protection, micro selfies, express transportation, disaster relief, wildlife observation, infectious disease monitoring, surveying and mapping, news reporting, power inspection, disaster relief, film and television shooting, creating romance, etc. Since there are more operating control components inside the drone, heat will be generated when it is working, so the inside of the drone needs to be cooled.

[0003] Publication number "CN213036061U" discloses "a heat dissipation shell for drones". By setting two concealable heat dissipation mechanisms on the shell, the heat in the shell is discharged through the copper tubes in the heat dissipation mechanisms, thereby reducing the failure rate of the drone. When not in use, the heat dissipation mechanisms can be stored to reduce the size of the drone. At the same time, the heat exchange is accelerated by setting a heat exchange box or heat exchange tube, thereby improving the heat dissipation efficiency of the shell.

[0004] The above-mentioned prior art still has the following disadvantages in the specific implementation process:

[0005] An electric telescopic rod, a circulating pump and a fan are provided inside, and coolant is provided in the copper tube, which is used for heat dissipation of the UAV, while increasing the overall weight of the UAV, affecting the flight speed and flight endurance of the UAV. In addition, the electric telescopic rod, the fan and the circulating pump all require electric drive, and consume many electrical appliances, which increases the cost of using the UAV and the subsequent maintenance and overhaul. At the same time, it is not convenient to overhaul, maintain and replace the components inside the shell, and the use effect is not good.

[0006] To address the above problems, we propose a lightweight UAV shell. Utility Model Content

DETAILED DESCRIPTION

[0028] This specific embodiment is a lightweight drone shell, such as Figure 1-Figure 9 As shown, the lightweight UAV shell includes a casing 1, a cover plate 2 is installed on the top of the casing 1 by bolts, a through groove is penetrated at the bottom of the casing 1, a heat conducting plate 3 is arranged at the inner bottom of the casing 1, and cooperates with the through groove, and two card slots 4 are relatively opened on the inner wall of the through groove, and the front end of the card slot 4 passes through the casing 1, and a card plate 5 is movably arranged in the card slot 4, and a heat dissipation fin 6 is fixed between the two card plates 5, which cooperates with the heat conducting plate 3, and notches 11 are opened on both sides of the casing 1, and two dustproof mesh plates 13 are relatively fixed at the bottom of the cover plate 2, which respectively cooperate with the notches 11 on both sides, and two fixing plates 7 are relatively fixed on the inner side of the cover plate 2, and a rotating shaft 8 is rotatably arranged on the fixing plate 7, and an air intake fan 9 and an exhaust fan 10 are respectively installed on the right end of the two rotating shafts 8.

[0029] The heat conducting plate 3 is used to transfer the heat at the bottom inner side of the casing 1 to the heat dissipating fins 6 during the operation of the drone, so as to cool and dissipate the heat at the bottom inner side of the casing 1. The card plate 5 cooperates with the card slot 4 to facilitate the installation, fixation, and removal and replacement of the heat dissipating fins 6. Under the action of the air intake fan 9, external air is easily introduced into the casing 1, and the exhaust fan 10 is combined to discharge the hot air inside the casing 1, thereby achieving the purpose of air flow inside the casing 1 and further improving the heat dissipation effect of the inner cavity of the casing 1. The dustproof mesh plate 13 effectively prevents external dust or foreign matter from entering the inner side of the casing 1.

[0030] Two T-slots 12 are relatively provided on the inner wall of the notch 11, and T-blocks 14 are fixed on the front and rear sides of the dustproof mesh plate 13, and the T-blocks 14 cooperate with the T-slots 12. A sealing groove 21 is provided at the bottom of the dustproof mesh plate 13, and a sealing strip 20 is fixed at the bottom of the notch 11. The sealing strip 20 is a hollow structure and cooperates with the sealing groove 21. Through the cooperation between the T-block 14 and the T-slot 12, it is convenient to adjust the dustproof mesh plate 13 to be stuck into the inner side of the notch 11. Combined with the cooperation between the sealing strip 20 with a hollow structure and the sealing groove 21, the tightness of the dustproof mesh plate 13 stuck on the inner side of the notch 11 is guaranteed, and external dust is prevented from entering the inner side of the casing 1 through the gap between the dustproof mesh plate 13 and the notch 11.

[0031] A U-shaped frame 15 is arranged between the two fixed plates 7, and the U-shaped frame 15 is fixedly connected to the cover plate 2. Support shafts 16 are rotatably arranged on both sides of the U-shaped frame 15, and pulleys 17 are arranged on the support shaft 16 and the rotating shaft 8. A transmission belt 18 is arranged between two adjacent pulleys 17 in the vertical direction. A dual-axis motor 19 is installed on the inner side of the U-shaped frame 15, and the output ends of the dual-axis motor 19 are respectively connected to the support shafts 16 on both sides.

[0032] A plurality of cantilevers 22 are fixed to the outer wall of the casing 1, and two landing gears 23 are fixed to the bottom of the casing 1. A rubber block 24 is arranged at the bottom of the landing gear 23, which effectively cushions the landing of the drone. A plurality of weight-reducing through holes are passed through the surface of the cantilever 22, and the landing gear 23 is a hollow structure, which reduces the overall weight of the drone.

[0033] A plurality of locking screw holes are provided on the surface of the card plate 5 , and a plurality of locking bolts are provided at the bottom of the housing 1 . The locking bolts cooperate with the threads of the locking screw holes to facilitate fixing the card plate 5 inside the card slot 4 , thereby facilitating the installation, fixation, removal and replacement of the heat dissipation fins 6 .

[0034] Example:

[0035] When in use, first adjust the card plate 5 to slide into the corresponding card slot 4, thereby driving the heat dissipation fins 6 to slide into the bottom of the heat conduction plate 3 and contact the heat conduction plate 3, and at the same time, fix the card plate 5 into the card slot 4 through the locking bolts, so that the heat dissipation fins 6 are installed and fixed;

[0036] Secondly, adjust the T-shaped block 14 to be aligned with the T-shaped slot 12, and move the cover plate 2 toward the upper port of the casing 1. When the cover plate 2 covers the upper port of the casing 1, the dustproof mesh plate 13 is driven to be stuck inside the notch 11, and the sealing strip 20 is stuck in the sealing slot 21 at the bottom of the dustproof mesh plate 13, and then the cover plate 2 is fixedly connected to the casing 1 by bolts;

[0037] During the operation of the drone, the heat at the bottom of the inner side of the casing 1 is transferred to the heat dissipation fins 6 through the heat conduction plate 3. At the same time, the fins of the heat dissipation fins 6 are located outside the casing 1. During the flight of the drone, the heat dissipation fins 6 are cooled by the flow of external air, thereby achieving the purpose of cooling and dissipating the inner bottom of the casing 1.

[0038] At the same time, the dual-axis motor 19 runs, driving the supporting shafts 16 on both sides to rotate synchronously. Under the cooperation of the pulley 17 and the transmission belt 18, combined with the rotation cooperation of the rotating shaft 8 and the fixed plate 7, the rotating shafts 8 on both sides are driven to rotate synchronously, thereby driving the air intake fan 9 and the exhaust fan 10 to rotate synchronously. The external air is introduced into the inner side of the casing 1 through the dustproof mesh plate 13 on the left side through the air intake fan 9, and the hot air inside the casing 1 is discharged to the outside through the dustproof mesh plate 13 on the right side in combination with the exhaust fan 10, thereby achieving the purpose of air flow inside the casing 1, and then achieving the purpose of cooling and dissipating the heat inside the casing 1.

[0039] Compared with the prior art, the utility model drives the support shafts 16 on both sides to rotate through the dual-axis motor 19, and replaces the air inside the casing 1 with the cooperation of the air inlet fan 9 and the exhaust fan 10. At the same time, with the cooperation of the heat conducting plate 3 and the heat dissipating fins 6, the bottom of the inner side of the casing 1 is further cooled and dissipated, which effectively improves the heat dissipation effect during the operation of the drone, and does not require the installation of multiple electrical appliances. It solves the problem that the electric telescopic rod, the circulating pump and the fan are provided in the prior art, and the coolant is provided in the copper tube for the heat dissipation of the drone, while increasing the overall weight of the drone. At the same time, it solves the problem that the use of the electric telescopic rod, the circulating pump and the fan in the prior art all require electric drive, which increases the use of the drone and the subsequent maintenance and repair costs.

[0040] When the inner parts of the casing 1 are inspected and maintained at a later stage, it is only necessary to remove the cover plate 2, and drive the dust screen 13 away from the notch 11 through the cover plate 2, so that the inner parts of the casing 1 are exposed through the notches 11 on both sides, which is convenient for the staff to carry out inspection, maintenance and replacement operations;

[0041] At the same time, it is convenient for the staff to inspect and maintain the air inlet fan 9, the exhaust fan 10 and other components.

[0042] It should be further explained that the installation structure, connection method or setting method of each component in the utility model are all common mechanical methods, and they can be implemented as long as they can achieve their beneficial effects. At the same time, the dual-axis motor 19 in the utility model is purchased on the market, and technical personnel in this field can install and use it according to requirements.

[0043] All technical features in this embodiment can be freely combined according to actual needs.
